Description

Technical Field

[0001] The utility model relates to the field of cast-in-place concrete structure steel cage binding construction, in particular to a large-volume special-shaped cap steel cage. Background Art

[0002] When constructing a concrete structure, it is necessary to tie the steel bars first and then pour the concrete. To improve the efficiency of on-site construction, the steel cage is usually tied on-site and transported to the site for installation. However, for large-volume special-shaped cast-in-place concrete caps, the transportation and hoisting of the steel cage are a huge challenge due to their huge size, and the steel cage is easily deformed during the hoisting and transportation process. If the partial tying method is adopted, the concrete is prone to cracking and deformation in the later stage due to the discontinuous steel bars. Utility Model Content

[0003] The utility model aims to overcome the deficiencies in the prior art and provide a large-volume special-shaped cap reinforcement cage.

[0004] This large-volume special-shaped foundation steel cage includes a support steel cage, a tie beam steel cage and U-shaped locking bars. The ends of the support steel cage and the tie beam steel cage are provided with annular butt bars. The annular butt bars of the support steel cage and the tie beam steel cage overlap. The U-shaped locking bars are inserted into the overlapping area of ​​the annular butt bars to form a large-volume special-shaped foundation steel cage. The tops of both ends of the U-shaped locking bars are provided with outward bending parts.

[0005] Preferably, the support portion steel cage and the tie beam portion steel cage both include planar steel bars and vertical steel bars.

[0006] Preferably, the annular butt reinforcements on the support portion reinforcement cage and the tie beam portion reinforcement cage are aligned with each other in the plane and staggered with each other in the vertical direction.

[0007] Preferably, the annular butt reinforcement is a smooth steel bar, the ends of the annular butt reinforcement of the support portion steel cage and the tie beam portion steel cage overlap, and the U-shaped locking bar is stuck in the overlapping area of ​​the two annular butt reinforcements.

[0008] Preferably, locking openings are provided on the upper and lower sides of the annular butt reinforcement, which are outward protrusions and have a width greater than the diameter of the U-shaped locking reinforcement; the annular butt reinforcements of the support part steel cage and the tie beam part steel cage overlap, the locking openings on the two annular butt reinforcements are aligned, and the U-shaped locking reinforcement is stuck in the locking openings.

[0009] Preferably, the U-shaped locking rib is provided with an outward bending portion, and the end of the bending portion is parallel to the length direction of the U-shaped locking rib, and the two bending portions are respectively clamped on the upper and lower sides of the annular butt rib.

[0010] The beneficial effects of the utility model are:

[0011] 1) The large-volume special-shaped cap reinforcement cage is composed of the support part reinforcement cage and the tie beam part reinforcement cage, which are tied in sections. The load of each part of the reinforcement cage is greatly reduced, reducing the difficulty of transportation and hoisting operations.

[0012] 2) Annular butt reinforcements are provided on the two parts of the steel cages respectively. The ends of the annular butt reinforcements are staggered to form an insertion space for the U-shaped locking reinforcements. The U-shaped locking reinforcements are inserted to achieve rapid butt reinforcement and locking of the two parts of the steel cages, thereby improving on-site construction efficiency, ensuring butt reinforcement strength, and avoiding cracking and deformation of the cap concrete.

[0013] 3) It is also proposed to set locking openings on the upper and lower sides of the annular butt ribs, and the two annular butt ribs overlap until the locking openings are aligned. The bent parts at both ends of the U-shaped locking ribs are respectively stuck in the upper and lower sets of overlapping locking openings, so that the U-shaped locking ribs are not easy to fall off after being fixed.
